NITED STATES W'AL TER R. TAYLOR, OF CHICAGD, ILLINOIS.

OIL BURNER.

Application filed July 19,

To all whom it may concern:

Be it known that I, lVALrnn R. TAYLOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil Burners, of which the following is a description.

My invention belongs to that general class of devices termed oil burners, and adapted to vaporize hydrocarbons, mixing the same with a suitable quantity of air and delivering the mixture at suitable burners. where it may be employed for heating, cooking or other desired purposes.

It has for its object the construction of a device of the character mentioned which shall be simple, effective and economical in its construction and effective in its operation. To this end it consists in the novel construction, arrangement and combination of parts herein shown iI1(lClSCIll)6Cl,RI1Cl more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a top plan view of a simple form of burner illustrating one form of my device;

Figure 2 is a vertical section on line 22 of Figure 1, illustrating the preferred form of construction of the same;

Figure 3 is a section taken substant ally on line 3-3 of Figure 2, showing the receiving chamber;

Figure 4 is a section taken substantially on line 4-4: of Figure 2; a t

Figure 5 is a plan view of a slightly modified form; and

Figure 6 is a fragmentary view illustrating burners arranged at the vertical sides, as well as at the top of the burner.

In the drawings, 1 illustrates the vertical walls of an annular chamber 2, 3 top provided with suitable burners 4, and 5 indicates the bottom of the chamber. In the center of the chamber is avertical well or opening 6 enclosed by a circular wall 7. Arranged below the chamber just described is a receiving chamber 8, which in the form shown, at one end is provided with an ad-- justable cap 9 having formed therein a small orifice 1O through'which the vapor is forced. The receiving chamber is also pro vided with an air chamber 11. The receiving chamber at its air chamber end is held in place by a dependingv sleeve 12 which being the,

is secured on the bottom of the device, as indicated in Figure 2. A set screw 13, passing through the sleeve 12. serves to maintam the receiving chamber in its proper adusted position in relation to the intake mixing and fuel pipe 14. The cap 9 also serves a similar adjusting purpose. The feeding and mixing pipe 14 is bent upwardly and backwardly at its other end 15, discharging into the annular chamber 2. k

The intake pipe 16 connected with a suit able source of supply under pressure, passes over a portion of the burners as indicated, becoming heated thereby, and passing down ward through the central opening referred to (6), at its lower end is connected with and discharges its contents into the receiv ing chamber 8. The equantity of hydrocarbon oil fed through. the pipe 16 may be controlled by a suitable valve, not shown,

and the pressure maintained therein in any preferred manner.

The operation of the device as thus described is as follows: The well or pan 17 arranged below the receiving chambcr may have a small quantity of wood-alcohol or other equivalent material for the purpose poured therein through the central opening 6 and heats the pipe of the receiving chamber. This is lighted and as the oil is gradually admitted, it is vaporized, and by reason of the pressure, the vapor is discharged through the orifice 10 into the open end of the combined feeding and mixing pipe 14. This action draws in a sufficient quantity of air at the open end of the pipe ll to produce a suitable burning vapor. This is conducted upward and backward, being delivered into the annular chamber 2 and thence escapes through the series of burners 4. The pipe 16 obviously may be heated in any preferred manner, but preferably by being maintained insuitable relation to the burner, and as it becomes heated to a high temperaturmithc oil delivered therethrough under pressure continues to discharge the vapor downward into the receiving chamber 8, andthence, as described, through the orifice 10.

I have found in actual practice that such burners are inclined to pulsate in their operation, due to the pressure caused by the vaporizing referred to and the varying pressure in the receiving chamber as the pressure therein rises and falls. This may be remedied to a considerable extent by care ful feeding. The ordinary operator, however, is often not sufficiently skilled to secure such a result and satisfactory operation is thus not secured.

To remedy this undesirable effect, I have provided the air chamber 11 connected with the receiving chamber 8 in any preferred manner. Thus as the pressure rises and tends to cause a pulsating flame, the pressure in the receiving chamber is equalized, that portion of the vapor near the orifice escaping therethrough, and that portion of the vapor more or less compressed into the air chamber, gradually equalizing the pressure in the receiving chamber in the well known manner.

If desired, a series of apertures 18 be formed in the inner wall of the central well 6, as shown in Figure. 2. These also will operate as burners and aid in suitably heating the intake pipe 16.

A similar result may be obtained as indicated in Figure 5, in which the inlet pipe is partially coiled about the upper face of the burner in such a manner as to be subjected to the heat from a larger number of the burners. As shown, the feed pipe 19 is coiled above the burners, finally extending downward as at 20., the result being substantially as set forth.

As shown in Figure 6, a series of burners 21 may be arranged about the vertical Wall 1, extending in a horizontal direction. This form is sometimes desirable for heating purposes, increasing the area of the burning section.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
